/*!
 * \file SkeletalModel.h
 * \brief This is the factored out skeletal model class
 *
 * Defining UNIT_TEST_SKELETALMODEL builds SkeletalModel class as a console unit test
 *
 * \author Mongoose
 *
 * \todo Start cutting off old hacks by simple force use of method interface.
 * Also move the publicly exposed attributes out  =)
 * Better animation system in general - this is memory wasteful
